The generic extension set 'G' is realy a base with the minimal set of
extensions needed to be comfortable (but not required) to run a
linux-bassed system. Similarly, we consider the custom to be about the
custom set of features (not about a custom core implementing such a
set).
As such, we allow that a core with the G set can have futher extensions
without requiring it to be configured as a custom set.
We drop the intermediate symbols with the prompts, and move the prompts
to the previously hidden symbols, and add a prompt for the I set.
This alows one to clearly see what the generic set is about, without
having to delve into the help and hunt the list of selected symbol.
Note however that the G set implies Zicsr and Zifencei, but we have no
prompt for thos two, because in Buildroot, we assume that they are
mandatory and always present, like the I set (which they previously were
part of).
